These ‘calyxes’ remain empty as long as the plant is not pollinated by a male plant. When it does get pollinated, these calyxes will fill up to hold and protect the plant’s babies: seeds. It is even thought that the resin on weed plants serves only that purpose in nature: to protect the plant’s offspring from burning in the sun.
You don’t have to be an expert on the plant to at some point have encountered the term ‘feminized’ in relation to cannabis seeds. As the name suggests, this means cannabis plants can be either female or male and in some cases have both sexes. This is what you need to know to spot Male, Female and Hermaphrodite cannabis plants in your garden:

Female cannabis plants are easy to spot once they start showing the first signs of flowering
When growing strains that are sensitive to stress, growers run a risk of their cannabis plants developing hermaphroditic traits – like the well-known Original Glue (Gorilla Glue #4). In our online seeds catalogue, you’ll find certain strains that are particularly resistant to stress.
If it is a plant that shows signs of continuous hermaphroditism during the first weeks of flowering, it is best to cut it directly if there is a danger of pollination of other females. If this happens to you, you should know that you can use the plant to make rubbing alcohol, for example. However, if you have to cut it with a more advanced flowering stage, I suggest you try to make BHO, because if the buds already have resin I feel that this is a better way to take advantage of a hermaphrodite.
There are also some hermaphrodite plants that can take out a few small bananas in a bud, visible and that can be removed with tweezers. In these cases it is also better to separate them carefully and, depending on the development of the buds, choose whether to bring forward the harvest or keep them under supervision until they finish their cycle. Once you’ve removed the bananas, you can use that weed like any other.
It was the human hand that began to isolate the best females for its own use, and by selection and crossing the dioecious traits were fixed in some pure varieties. From the best stable Landraces came the first hybrids, and from them most of the polyhybrids we know nowadays. The vast majority of cannabis seeds nowadays are of well-defined sex, but there are still genetics that can show hermaphroditism and this is what we will see here. What is a hermaphrodite cannabis plant and what can we do with it?
And if they are seeds from a hermaphrodite plant, can I use them?
Some specimens can take out 1 or 2 male flowers and nothing else, it happens sometimes with pre-flowers, in the fourth or fifth knot usually, that can be taken out and the plant will continue to flower as a female many times. It is convenient to keep an eye on these specimens if they are mixed with other females, in case at some point they take out some little banana (male flowers that come out in some hermaphrodite buds).
In the past this was not a problem, because cannabis was used for making fibres and the seeds were eaten, so every plant was valid. Then they started smoking the flowers after removing the seeds, as well as producing hashish centuries later, and they soon realized that female plants were much better for these purposes, or that they barely showed any male flowers.
Among cannabis plants we can find dioecious and monoecious specimens, that is, individuals that only show a defined sex and others that contain flowers of both sexes in the same plant. Originally they were all monoecious, as is the case with almost all varieties of industrial hemp as well as the vast majority of vegetables on the planet.
This is not always possible, because there are some varieties that have it very marked, intrinsic. But there are many others that only have a tendency to hermaphroditism, or a greater ability to produce flowers of the opposite sex. This tendency has a lot to do with the ability of genetics to withstand stress, those that are sexually pure, very few, endure much more stress without showing changes in their sex. If you want to stop them from showing it, consider the following factors:
If you want to try breeding, you’re going to need regular cannabis seeds, and Royal Queen Seeds offers a premium range. In contrast to feminized seeds that produce only female specimens, regular seeds offer a 50% chance of the plant being male or female.
Hermaphrodite cannabis plants come in two different forms: true hermaphrodites and “bananas”.
The former features distinctly male and female reproductive organs. Upon close inspection, you’ll notice pollen sacs occupying some nodes, and female flowers residing at others. When the pollen sacs rupture, the pollen will displace into the flowers, and the plant will effectively breed with itself. From there, it’ll go to seed and produce the subsequent generation.
HOW TO AVOID HERMAPHRODITE PLANTS IN YOUR GROW ROOM
Female cannabis plants are the main focus of casual growers looking to harvest a personal stash. But, depending on their genetics, female plants can look drastically different from one another. Some remain small, producing dense canopies and significant lateral growth. Others grow in excess of 3m, produce massive harvests, and look more like trees than regular garden plants.
See, the vast majority of plant species are monoecious, a term meaning they possess both male and female reproductive organs. These include edible plants, such as corn and squashes, that can readily fertilise their own flowers using their own pollen.
Several factors can cause female plants to start to develop pollen sacs—or exposed stamens—alongside their flowers. This trait means that plants don’t need to rely on a nearby male to burst their sacs and fertilise them. As we’ll discuss in a bit, this is actually a savvy survival mechanism and a display of nature’s genius. However, hermaphrodites aren’t desirable in the grow room or garden. Now, let’s discuss both types and how to avoid the issues they cause.
